First, Swift went back to her country roots to perform the Dixie Chicks' hit "Goodbye Earl," which she called her "go-to talent show song," with Maines.

Then, the "Bad Blood" singer surprised everyone by bringing Ellen DeGeneres to the stage to strut her stuff down the "Style" runway. The comedian even managed to one-up (or, dare we say, outshine) the songstress by showing up in an outfit more sparkly than hers.

Finally, Swift brought it home with a great performance of "You Oughta Know" with grunge icon Alanis Morissette. Now, we know how much T Swift loves a good breakup song, and as she noted on stage, the Morissette track from the '90s may just be "the greatest breakup song of all time." It was a perfect match.

Taylor Swift is pretty much living out her wildest dreams on stage.
